Light emitting diode, array substrate, light emitting device and display device

A light emitting diode, comprising:

• an anode, a hole transport layer, a light emitting layer, an electron transport layer and a cathode, which are sequentially disposed;
• and
• a first auxiliary electrode and a first insulating layer which are disposed on a side of the anode away from the hole transport layer, wherein the first insulating layer is located between the first auxiliary electrode and the anode, and the first auxiliary electrode is electrically insulated from the anode through the first insulating layer;
• and/or a second insulating layer and a second auxiliary electrode which are disposed on a side of the cathode away from the electron transport layer, wherein the second insulating layer is located between the second auxiliary electrode and the cathode, and the second auxiliary electrode is electrically insulated from the cathode through the second insulating layer.
